I've done modification of terrain elevation data at build time (both to the source GIS data, as well as within VPB), at post-build convert-time, and at run-time (during load and post-load). I'm working on packaging up some terrain tools that provide the framework for doing (some of) the above. It hasn't been published yet because it relied on some changes that Robert didn't accept into OSG, so I have to rework the structure to operate in a more supported fashion. But, I anticipate getting it out there this month. > Cheers, > Torben -- Chris 'Xenon' Hanson, omo sanza lettere Xenon AlphaPixel.com PixelSense Landsat processing now available! http://www.alphapixel.com/demos/ "There is no Truth.
